置。 A magnetic tape reproducing device in which various types of identification information are recorded at the beginning of each program information along with a plurality of program information, the device comprising: a tape drive means for running the magnetic tape; and a drive means for driving the tape drive means. a control means for controlling, a designation means for designating desired program information, a first detection means for detecting the identification signal from the read signal from the magnetic tape, and a radio frequency (RF) signal in the read signal. a second detection means for detecting that it is included;
specified program detecting means for detecting specified program information by the specifying means based on the identification information detected by the first detecting means, and the control means detects the magnetic tape in response to a high-speed search command. The magnetic tape is made to run at high speed in the forward direction, and when a detection output of the second detection means is generated during this high speed run, the magnetic tape is made to run in the reverse direction until the detection output disappears, and then the magnetic tape is run at high speed in the forward direction again. An information reproducing apparatus characterized in that the tape driving means is drive-controlled to gradually shift to .
